​
Improvements

  • Improved the default sort behavior for aggregations.
  • The SQL query IS NULL now seeks out empty values as expected.
  • Fixed a bug with the Fusion SQL service that prevented a collection from sharing a name with an collection alias.
  • Previously, SQL aggregations were limited to 250 aggregations. Now, the default limit is 5,000 aggregations, and the limit is configureable. To set the limit to 10,000 aggregations, use the following command: 
    curl -u USERNAME:PASSWORD -X POST -H 'Content-type: application/json' -d '10000' http://localhost:8764/api/apollo/configurations/fusion.sql.bucket_size_limit
  • Improved how multi-word synonyms are handled by query rewriting.

​
Bug Fixes

  • Fixed an issue with the XML Transformation index pipeline stage that prevented it from parsing information from an RSS feed.
  • Fixed a bug that sometimes caused the Token and Phrase Spell Correction Job to fail with an ArrayIndexOutOfBoundsException error.
  • Fixed a bug that prevented security trimming from working on the Alfescro connector in Fusion 4.2.4.
  • Fixed a bug that sometimes resulted in documents on CrawlDB being marked as incomplete when crawl operations were started and stopped multiple times.
  • Performance is improved in aggregation collections.
  • Fixed a bug that caused Head/Tail Analysis jobs to fail due to a misconfigured collection name.

​
Known issues

  • The Couchbase connector does not work with Couchbase versions 5 or later. This will be addressed in Fusion 4.2.6.
  • The FTP connector sometimes prevents files with non-English filenames from being indexed.
